Black mold in Dubai closet: DIY clean or call pro?« Back to Previous Page

Based on your description of recurring black spots on an interior closet wall in a Marina apartment, this is a classic case of mold growth driven by Dubai's high ambient humidity and microclimates created by year-round air conditioning. The spots are likely Cladosporium or Aspergillus, which thrive in the condensation that forms on cooler interior walls, especially within enclosed, poorly ventilated spaces like closets.

For a small, surface-level area (less than 1 square meter), a cautious DIY approach can be attempted. You must wear an N95 mask, gloves, and eye protection. Do not simply wipe or spray bleach, as this can aerosolize spores. Instead, use a detergent solution (e.g., diluted laundry detergent) and a microfiber cloth to carefully scrub the area. The goal is to physically remove the growth without spreading it. After cleaning, the area must be dried completely with a fan, and the underlying cause must be addressed. This is almost always inadequate ventilation. Leave the closet doors open and consider a small desiccant dehumidifier inside.

However, given that the issue has persisted for two years and is worsening with humidity, a professional inspection is strongly recommended. The mold may have penetrated the porous surfaces of the drywall or backing board, making surface cleaning ineffective. In the UAE, professional remediation companies like ours follow strict guidelines to contain the area, use HEPA filtration to remove airborne spores, and safely remove contaminated materials.

For a definitive assessment and to ensure it is handled according to Dubai Municipality standards, I advise calling our certified team for an inspection. We can identify the exact species and the moisture source. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com for a comprehensive solution.
